The aim is to get the washer off the bolt. The idea is the magnet is glued into the top section of the main bolt with epoxy. Which will hold the steel rod in place when the assembly is together. To open the puzzle you need to slam the base on a hard surface dislodging the rod and allowing you to remove the other parts of the puzzle so you can remove the washer.

<p>this would be sooooo cool to get my friend back for his </p><p>puzzle a few weeks ago. </p>

<p>It does not look so nice and shiny but according to your instructable I MADE IT! Thank you for posting .. I gave it to many of my friends but noone solved it.</p>

<p>Nice, maybe you could shine it up a bit on a buffing wheel if you have access one.</p>

Yeah that's a good idea - I will certainly try it.

<p>very nice. A video would do wonders...</p>

<p>I agree a video would be great at demonstrating this!</p>

<p>This'll be great for giving my friends migranes.</p>

<p>Nice.....</p>

<p>Cut the bolt where the nut goes. Drill the parallel holes in the top and bottom half. Glue the magnet into the top half, put the rod into the bottom part. Put all together and drill the cross hole. Then just put the cross bolts in. </p><p>The cut can't be seen when the puzzle is together as it's covered by the bolt.</p>

<p>Regarding your plan to braze the hole after installing the rod and magnet, heating up a rare earth magnet will de-magnitize it. This would also probably melt the epoxy used to secure the magnet. You could put a slight taper on a piece of brass rod and drive that into the hole instead. Or you could probably fill the hole with JB weld if you used galvanized hardware and not have it be noticed.</p>

<p>Greetings, So that is what happened to My pick up tool. I never could even re -magnitize it using My H/F magnitizer - de - magnitizer. Thank You. ~(:-})={</p>

<p>well they could put the steel rod in braze it and using plastic tweezers or something similar to insert the magnet afterwards through the side hole.</p>

<p>That was just what I was thinking.</p>

<p>Isn't JB weld epoxy too? Metal dust suspended in epoxy?</p>

<p>Simply Fantastical good sir.</p>

<p>Well done, sir, well done!</p>

<p>Tthanks for the encouraging comments guys.</p>

<p>Good instructable and an improvement on the one in the link you have provided.</p>

Very nice finishing

I've seen this puzzle made as your friend suggested. It is a bit of work, but the finished product looks a bit better. Also the brazed portion is a bit harder than the bolt. It would seem that it would hold up better, and not be dinged or flattened.
